A Trachyphlixus (genus Curculionidum), et uajia, corpus. 



The insignificant little brown Curculionid from which I 

 have compiled the above stinictural diagnosis, and which is 

 manifestly one of the most indigenous of tlie St.-Helena Co- 

 leoptera, has so much the jirimd facie appearance, in its short 

 oval outline and the mud-like scales and setaj with which it is 

 clothed, of a minute TrachyiMoeus that it required a close 

 examination to convince me that it should not be referred to 

 that group. When carefully inspected, however, it will be 

 seen to have many essential points of difference ; for not only 

 is its rostrum more abbreviated and conical, and truncate (in- 

 stead of ti-iangularly scooped out) at the tip, but its scrobs is 

 likewise more bent downwards (and that veiy suddenly) be- 

 neath the still smaller and less prominent eye, from which, 

 consequently its lower edge is much more remote ; its antennaj 

 also are a trifle less incrassated, and inserted appreciably 

 nearer to the apex of the rostrum ; and its feet have their third 

 joint less broadly bilobed, and their claws a little more deve- 

 loped. On the whole, I should say that it had more in com- 

 mon with my Madeiran genus Scoliocerus than with Trachy- 

 phloeus proper ; nevertheless the position of its rostral grooves 

 and its less curved scape will of themselves suffice to separate 

 it therefrom.

T. breviter ovatum, squamis nigro-bruaneis quasi lutosis densissime 

 tectum setisque fulvo-cinereis subcrectis parce obsitum, (subter 

 squamis) jnceum ; protborace subter squamis grossissime punc- 

 tato, punctis maximis, inter se subconflueutibus ; clytris subter 

 squamis valde .profunde striato-punctatis, puuctis magnis et ar- 

 gute determinatis.

Many examples of this obscure little Trachypklceus-likc 

 weevil, which were taken by Mr. Melliss at St. Helena, are 

 now before me ; and there can be little doubt, I think, that it 

 is a tnily aboriginal form. Its dull muddy-brown surface, 

 which is thickly incrusted with scales and more sparingly 

 beset with short suberect fulvo-cinereous setae, will be seen, 

 w/ien the covering is abraded or removed, to be most coarsely, 

 but Avidely sculptured, — the punctures on the prothorax being 

 enoi'mous, though rather in-egular and subconfluent, whilst 

 those which stud the clytral stria) arc perhaps not quite so 

 large, but deep and better defined.
